Relevance. It is important to learn the psychophysiological features of the young people, who smother dent alveolar anomalies.

Purpose. The goal of the investigation was the learning of the features of the psychophysiological status of the young people with dent alveolar anomalies, taking into account a method of orthodontic treatment.

Materials and methods. Probands were divided into 4 groups depending on the types of used orthodontic devices. The day stress levels and a quality of the night sleep of the young people smothering dentoalveolar anomalies, taking into account a way of the orthodontic treatment (vestibular or lingual bracket-systems), were investigated. The device, which allowed to analyze the variability of the heart rate, was used for the identification of the features of the psychophysiological status. The indicators of the day stress level and the night sleep quality were examined among all investigated groups. The indicator of the day stress level was taken in percents, and the night sleep quality indicator was taken with the restoration coefficient - in standard units.

Results. Young people, using vestibular bracket-systems, were registered productive psychophysiological status with gratifying and good restoration coefficient scores. People, who received orthodontic treatment with lingual bracket-systems, were noticed the increasing their day stress level and the reducing their night sleep quality during the whole clinical-physiological research. 

Conclusion. Collected findings are needed to use choosing the treatment way of dentoalveolar anomalies of the persons, whose professions are connected with their specific living conditions and physical and extreme factors.
